Abstract
OBJECTIVE: to assess patient knowledge of heart failure by home-based measurement of two NOC Nursing Outcomes over a six-month period and correlate mean outcome indicator scores with mean scores of a heart failure Knowledge Questionnaire. METHODS: in this before-and-after study, patients with heart failure received four home visits over a six-month period after hospital discharge. At each home visit, nursing interventions were implemented, NOC outcomes were assessed, and the Knowledge Questionnaire was administered. RESULTS: overall, 23 patients received home visits. Mean indicator scores for the outcome Knowledge: Medication were 2.27±0.14 at home visit 1 and 3.55±0.16 at home visit 4 (P<0.001); and, for the outcome Knowledge: Treatment Regimen, 2.33±0.13 at home visit 1 and 3.59±0.14 at home visit 4 (P<0.001). The correlation between the Knowledge Questionnaire and the Nursing Outcomes Classification scores was strong at home visit 1 (r=0.7, P<0.01), but weak and non significant at visit 4. CONCLUSION: the results show improved patient knowledge of heart failure and a strong correlation between Nursing Outcomes Classification indicator scores and Knowledge Questionnaire scores. The NOC Nursing Outcomes proved effective as knowledge assessment measures when compared with the validated instrument.
Highlights
Patients’ knowledge deficits regarding heart failure (HF), its management, and self-care measures have been considered predictors of clinical instability and consequent readmission[1,2,3]
Diverging from our findings, this study identified a significant improvement in the Knowledge: Treatment Regimen outcome in group 2 alone[15], only one home visit was performed
The findings of this study revealed a significant improvement in Nursing Outcomes Classification (NOC) outcomes that assess knowledge of disease and its management among patients with HF after the implementation of nursing interventions over the course of four home visits
Summary
Patients’ knowledge deficits regarding heart failure (HF), its management, and self-care measures have been considered predictors of clinical instability and consequent readmission[1,2,3]. In addition to followup at HF clinics and phone-based monitoring, home visits (HVs) have proved effective in this regard[5,6,7] Among these approaches, HVs stand out as a new frontier in the care of chronic patients and permit isolating the effects of nursing interventions from the effects of interventions pertaining to other professions involved in patient care[8,9,10]. Within this perspective, the present study sought to assess patient knowledge of HF by home-based measurement of two Nursing Outcomes Classification (NOC) outcomes over a six-month period and measurement of the correlation between mean outcome indicator scores and mean scores on an HF Knowledge Questionnaire (KQ) previously validated for use in Brazil[11]. The relevance of this study lies in its use of an intervention protocol based on the Nursing Interventions Classification (NIC) in the measurement of NOC outcomes during home visits, and in the assessment of the correlation between NOC outcomes and a validated patient knowledge evaluation instrument
